Serious Fueling for Serious Competition

If you’re pushing your Duramax to the limit at the track or during sled pull competitions, stock injectors just aren’t going to cut it. That’s where the Industrial Injection Reman 50% Over Injector comes in. Designed for the 2004.5 to 2005 GM Silverado and Sierra 2500HD and 3500HD with the 6.6L LLY Duramax, these injectors deliver the extra fuel your engine demands when every bit of power counts. Flowing 34 liters per minute, these remanufactured injectors provide a 50% increase in fuel over stock, giving you the capacity to support big power builds without starving your engine under load. Whether you're building a purpose-built race truck or going all-in on your pulling rig, these injectors help you take performance to the next level.

Designed for High-Output Duramax Builds

This injector is sold individually, but you’ll need to purchase a full set of eight to complete your build. A refundable core charge applies, provided your old injectors are returned in rebuildable condition. These injectors are specifically designed for competition use, making them ideal for setups that require high fuel demand far beyond what the factory injectors can provide. From the moment you roll onto the track or hook to the sled, you’ll feel the difference in throttle response and power delivery. If you’re chasing more horsepower and want proven fueling performance to back it up, Industrial Injection’s 50% Over Injectors are built to get the job done.

Fits: 2004.5, 2005 GM Silverado/Sierra 2500HD/3500HD 6.6L Duramax LLY
